TYPOGRAPHICAL COMPOSING AND LINE-CASTING MACHINE.

Specification of Letters Patent. Patented N 14 1911.

Application filed August 25, 1911.

Serial No. 646,013.

To all whom it may concern:

Be it known that I, HEINRICH DEGENER, a subject of the German Emperor, residing at 26 Hollmannstrasse, Berlin, in the German Empire, have invented new and useful Improvements in Typographical Composing and Line-Casting Machines, of which the following is a specification.

This invention relates to typographical composing and line-casting machines such as those known commercially under the trade mark Linotype, and particularly to those machines which are provided with circulating matrices each of which has two formative cavities one above the other, and which matrices can be assembled with either of the said cavities in the composing line. In these machines there are devices already known by which the descent of the matrices into the assembler elevator is arrested be fore the matrices reach their lowest position therein, and by which, during their advance along the said elevator, or during the ascent of the latter, the said matrices can be brought into the lower position, by intervals or gaps in the matrix-supporting ledges.

According to the present invention the descent of the matrices is arrested by a stop which is so arranged that the said matrices strike it at the middle art of their feet as distinguished from existing arrangements whereby their descent is arrested by their bottom lugs coming into contact with an adjustable ledge or stop; by these means much wear, detrimental to good alinement of the matrices, is avoided.

In the accompanying drawing which shows the preferred constructional form of the invention, Figure 1 is a front elevation partly in vertical section of the assembler elevator and other adjacent parts, and Fig. 2 is a plan partly in horizontal section of parts of Fig. 1.

The construction of the assembler elevator l and of the fixed ledge 2 and movable ledge 3 which hold the matrices in their different levels, corresponds with that of existing arrangements, with the exception that instead of the short stationary ledge which hitherto has been employed for stopping the descent of the matrices a block 4 is arranged at the entrance end of the assembler elevator, between the two sides of the latter and not adjustable as to height. The matrices 5 in their descent are allarrested by this block 4 at the same height, and they contact with the block only with the middle part of their feet, the lugs involved in the subsequent alinement taking no active part in this actual stoppage. If the movable ledge 3 is in the position shown in Fig. 2, that is to say with its right-hand end at a distance away from the block 4, the matrices on moving leftward off the block 4, will fall on to the lower ledge 2. If the matrices are to remain in their upper position, the movable ledge 3 is pushed into its rightmost position, so that its right-hand end is flush with the right-hand end of the assembler elevator. The top surface of the block 4 may be somewhat higher than the movable ledge 3, so that when the latter is in its lastnamed position, the matrices will not strike upon the ledge. right-hand end of the line are to be retained in their upper position, it is necessary to move the ledge 3 into its rightmost position sothat it will support those matrices during the upward movement of the assembler elevator.

In order to prevent the matrices falling between the block 4 and the known star wheel 6, the block 4 may, with advantage be provided with a nose or rib 7, and the arms of the star wheel with corresponding recesses 8 to clear the said rib, by which arrangement the block can extend well beneath the wheel 6 without interfering with its rotation.

The space-bars descending from their magazine can as a rule, without difliculty, be assembled in line, their feet being beveled and the block 4 not projecting very far into the line. But in order to remove all possibility of the space-bars being interfered with by the block 4 the latter may be movable ina horizontal direction, for which purpose it can be provided with a draw rod 9, which is guided in the machine frame and so operated by the space-bar escapement mechanism that at each release of a spacebar the block 4 will be drawn rightward and, after the space-bar has taken up its proper place in the assembling line, returned to its normal position. The mechanism for withdrawing the block 4 as last described is not shown in the drawing, and it may be of any desired construction.

When the matrices at the Having thus. described my invention, declare that/what I claim and desire to secure by Letters Patent is machine out-of operative position to permit the space bands to enter the line without'interference with the stop device.

2. In a typographical composing machine,

15 the assembler elevator provided with means to sustain the matrices at different levels, combined with a stop, normally in position to arrest the descent of the matrices, the said stop being movably arranged to permit it to be shifted horizontally to an abnormal position in the machine; whereby the space bands will be permitted to pass into the line without interference with the stop.

In witness whereof I have hereunto set my hand in the presence of two witnesses.

HEINRICH DEGENER.
